Batch Music Generation

Generates royalty-free background music / BGM from multiple prompts in batch, without vocals or lyrics. Supports various styles and duration control (30-120 seconds).

meitu batch audio-music-generate

Note: Batch processing is available from meitu-cli v2.1.1 onward. Please upgrade if you're on an older version.

Two input modes supported:

  1. Directory scan mode — Scan a directory of text files (one prompt per line) via --input-dir, with a uniform duration set by --duration.
  2. Config file mode — Specify a YAML or JSON config file via --config for per-task custom parameters.
